Irradiation-Induced Magnetism in Carbon Nanostructures

Block Copolymers used to organize nanostructured magnetic materials

Nitrogen (N15) and carbon (C12) ion implantations with implant energy of 100 keV for different doses were performed on nanosized diamond (ND) particles. Magnetic measurements on the doped ND show ferromagnetic hysteresis behavior at room temperature. The saturation magnetization (Ms) in the case of N15 implanted samples was found to be higher compared to the C12 implanted samples for dose sizes greater than 1014 cm-2. The role of structural modification or defects along with the carbon-nitrogen (C-N) bonding states for the observed enhanced ferromagnetic ordering in N15 doped samples is explained on the basis of x-ray photoelectron spectroscopy measurements.

Los Alamos National Laboratory scientists have designed a new type of nanostructured-carbon-based catalyst that could pave the way for reliable, economical next-generation batteries and alkaline fuel cells, providing for practical use of wind- and solar-powered electricity, as well as enhanced hybrid electric vehicles.
In a paper appearing recently in Nature Communications, Los Alamos researchers Hoon T. Chung, Piotr Zelenay and Jong H. Won, the latter now at the Korea Basic Science Institute, describe a new type of nitrogen-doped carbon-nanotube catalyst

Depleted Uranium and our troops and all those

Oct. 2006: President George W. Bush signed the Department of Defense Authorization legislation. The House amendment was authored and introduced by Rep. Jim McDermott (D-Wa.) ordering a comprehensive study - with a report due in one year - on possible adverse health effects on U.S. soldiers from the U.S. military's use of DU - Depleted Uranium. The Senate companion bill was backed by Joe Lieberman of Conn., a democrat at the time. (McDermott's Web site: )
